Electrochemical Additive Manufacturing: Challenges and Opportunities

Dear Colleagues,

Additive manufacturing offers multiple benefits to create 3D metallic nanostructures: increased sustainability by lowering the resource effort needed, increased 3D freedom in design and manufacturing to demand. Additive manufacturing methods are already implemented in the automotive, machining, aerospace, electronics and medical products,

In the macroscale, additive and subtractive methods are used to produce CMM (composite meta materials) from micromachining to establish mesoscale additive manufacturing like selective laser melting and sintering.

The importance of the size scale is given by the application the metamaterial is designed for.

In the microscale, subtractive methods with the necessary resolution become rare and the available methods such as focused Ion beam milling (FIB milling), are directional and the degree of freedom is limited. Electrochemical additive manufacture methods are an interesting alternative to others as they allow to reach the microscale as well as their relatively cheap as most are operated at ambient or slightly elevated temperature and ambient pressure. While the technique is mainly used to create thin films with the following methods it is possible to create elaborate 3D structures.

Nevertheless, Technical challenges arise from the multistep production method and electrodeposition challenges from influence of the template on the electrodeposition.

The present special issue is devoted to gather these efforts of the research community worldwide and present the most relevant technologies allowing the use of the template assisted electrodeposition for diverse research communities.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electrochem is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
